Instruments to assess individuals' self-efficacy for the control of addictive behaviors have been useful for monitoring behavior change, predicting maintenance of treatment gains, and identifying potential relapse situations. The Gambling Self-Efficacy Questionnaire (GSEQ) was developed to assess perceived self-efficacy to control gambling behavior. A demographically diverse sample of 309 adult gamblers completed an initial set of 42 items, of which 16 were selected to form the final version of the GSEQ. The GSEQ showed high internal consistency ( = .96) and good test-retest reliability (r = .86). A factor analysis provided some support for a unitary factor structure. As expected, GSEQ scores were negatively correlated with reports of problematic gambling behavior. Participants experiencing problems related to their gambling behavior scored significantly lower on the GSEQ than those who were not experiencing gambling problems. This psychometric examination of the GSEQ supported its potential utility for treatment planning and outcome evaluation with problem gamblers.  相似文献

Recent meta-analyses and experimental designs of batterer program evaluations suggest little or no program effect. This finding may be compromised by a variety of analytical issues. Instrumental variable analysis addresses some of these issues, especially the relationship of program dropout to batterer reassault. This method of analysis was, therefore, used to test for program effect in a multi-site evaluation. The sites were three well-established batterer programs using a gender-based, cognitive-behavioral approach (n = 640). Completing a batterer program reduced the likelihood of reassault by 44% to 64%, depending on the specification used. Completing a 3-month program appeared to be as effective as completing a 5 1/2- or 9-month program. This moderate effect is an accomplishment considering the problems associated with the program participants and the inconsistency in the criminal justice system at the research sites. The findings remain tentative because of weak instrumental variables for reassault, but do confirm the need for more complex analyses of program effect.  相似文献

To provide first-rate services to students, college health services need the best possible staff. Managers and supervisors play a critical role in guiding the work of their employees so as to enhance performance. Reference checks for new employees and regular performance appraisal dialogues for ongoing employees are important tools in this process. The author discusses these issues and suggests formats for reference checks and performance appraisals.  相似文献

Norwalk-like viruses (NLVs) are transmitted by fecally contaminated food, water, fomites, and person-to-person contact. They are a leading cause of acute gastroenteritis epidemics in industrialized countries. NLV outbreaks are characterized by a 12- to 48-hour incubation period; nausea, vomiting, and diarrhea for 24 to 72 hours; and high secondary attack rates. NLV infections spread rapidly on college and university campuses because of close living quarters, shared bathrooms and common rooms, many food handlers, popular self-service salad bars in dining halls, and person-to-person contact through sports and recreational activities. The illness is generally mild and self-limited but an outbreak can strain the resources of campus health services and cause high absenteeism among both students and staff. Treatment is primarily through antiemetic medication and oral rehydration. Prevention and control of NLV outbreaks rests on promoting hand washing; enforcement of strict hygiene in all food preparation areas; and prompt, rigorous cleaning of potentially contaminated areas where someone has been ill.  相似文献

1. Consumers who elect to use natural products are electing to do more than simply use a product. Their choice is an act of self-empowerment. 2. Education is necessary because these products most often are not being obtained in a professional, consultative setting but rather in chain discount department stores and supermarkets. 3. If consumers choose to address their health concerns using a natural-based treatment plan, consultation with a health care practitioner who shares this shift in perspective and who follows the literature is important. 4. A paradigm shift could be on the health care horizon, which when complete would make herbs and other natural products part of mainstream health care practice.  相似文献

Three influences in American education during the past decade -- increased parental involvement, an emphasis on accountability and student outcomes, and the refinement of assessment technologies -- are reflected in the 1997 Amendments to the Individuals with Disabilities Education Act [31]. Relevant assessment provisions contained in IDEA 97 are reviewed, including requirements for (a) parental participation in the review and planning of student evaluations and eligibility decisions; (b) the participation of students with disabilities in statewide assessments; (c) the use of assessments that have treatment utility; and (d) data-based evaluation of student progress. Assessment characteristics and methods that are consistent with IDEA 97 requirements are described. Examples include problem-solving assessment; functional behavioral assessment; and direct assessment approaches such as naturalistic observation, analogue assessment, and self-monitoring.  相似文献

When candidates assume issue positions opposite those of their sponsoring political party do citizens recognize these positions? Relatedly, what role do candidates' actual issue positions play in citizens' perceptions of their issue positions? Examining citizens' perceptions of 1996 and 1998 House candidates' position on abortion, this research finds that citizens' perceptions are shaped largely by partisan and, to a lesser extent, gender stereotypes. However, candidates' individuating positions on abortion influence perceptions of the candidates' position, but the effects are considerably stronger for perceptions of Republican candidates. Democratic candidates are likely to adopt anti-abortion positions in districts characterized by lower than average levels of political awareness and education, reducing the likelihood their party-contradicting position is accurately perceived. In contrast, Republican candidates adopt a pro-choice position in districts characterized by high education and political awareness, increasing the likelihood their position is accurately perceived.  相似文献

Adolescent substance use has become a serious concern nationwide. Although there are many ways of viewing adolescent substance use, family influence has been established as one of the strongest sources of risk and protection. A review of the literature indicated relevant theories for understanding adolescent substance use and specific family-based variables influencing adolescent substance use. In general, there seems to be a relationship between adolescent substance use and family-based risk and protective factors. Relevant theories identified in the literature review include family systems theory, social cognitive theory, social control theory, and strain theory. Specific family-based risk and protective factors include family relationships such as with siblings and parents and family characteristics such as ethnicity and religious backgrounds. Future implications for research and prevention/intervention in relation to family-based risk and protective factors are discussed.  相似文献

This was a preliminary study to evaluate the effectiveness of a tobacco prevention program on knowledge, attitude, intention, and behavior of tobacco use among fourth-grade students in four north central Florida counties. The results suggest that the program was effective in improving students' knowledge, attitudes, and intention toward not using tobacco products. Data analysis showed that students in the education group had a greater improvement in knowledge than the comparison group. Students in the education group also improved their attitude and intention scores while the comparison group did not show any improvement. The results also indicated positive responses from the students. In addition, teachers also gave a very positive response to the program.  相似文献

It is nothing new to suggest that money has meaning. Whether or not one accepts Freud's (1908)linkage of money and feces, within our culture money is frequently seen as a direct pathway to feelings of power, agency, self-directedness, and personal satisfaction. Trachtman (1999) states, Money, psychologically speaking, is our projection onto coins, bills, bank accounts, and other financial instruments of our beliefs, hopes, and fears about how those things will affect who we are, what will happen to us, and how we will be treated by others or by ourselves...(Trachtman, 1999, p. 283). Yet this material is often unavailable for therapeutic exploration or understanding until it explodes into the therapy, often in unmanageable and countertherapeutic ways. This article will look at some of the ways in which money can be utilized to negotiate the ever-changing tensions between self and other, object and subject, intrapyschic and interpersonal, connection and separation that appear in every relationship. In particular, it will explore some ways that money issues within the therapeutic relationship can be turned into significant tools for understanding and working with anxieties about connection and separateness, both within and outside the therapeutic dyad.  相似文献
